Gan-Gross-Prasad Conjecture for U(p,q)

Representation Theory 2022-01-03 v2

Abstract

In this paper, we give a proof of the Gan-Gross-Prasad conjecture for the discrete series of U(p,q). Given a discrete series representation D(λ)D(\lambda) in terms of the Harish-Chandra parameter, the restriction of D(λ)D(\lambda) to U(p-1,q) contains D(μ)D(\mu) as a subrepresentation if and only if λ\lambda and μ\mu interlaces in a very special way.
